Which condition is most often described by leg pain with exertion relieved by rest?

• A. Intermittent claudication
• B. DVT
• C. Lymphedema
• D. Raynaud's phenomenon

Answer: (A)

Intermittent claudication due to peripheral artery disease presents as leg pain with exertion that improves with rest. When the leg muscles work harder, they need more oxygen. Narrowed arteries in PAD can’t increase blood flow enough, so the muscles become ischemic and produce cramping or aching pain. Once you rest, oxygen demand drops and blood flow can meet it again, so the pain goes away. This pattern is what sets intermittent claudication apart from other leg conditions. Deep vein thrombosis typically causes swelling, warmth, and tenderness rather than exertional pain that is relieved by rest. Lymphedema involves chronic swelling from lymphatic disruption, not ischemic pain tied to activity. Raynaud’s phenomenon causes color changes, numbness, and cold sensitivity from vasospasm, usually in response to cold or stress, not exercise-induced leg pain.
